A national team of researchers led by Penn State Professor of Oceanography Raymond Najjar (departments of meteorology and geosciences) have commenced work on a NASA-funded study to determine if the estuaries and tidal wetlands along the contiguous U.S. coast are net emitters or absorbers of carbon dioxide (CO2). The three-year, $1.2-million study is the first to look at the entire contiguous U.S. estuarine and tidal-wetland system.

Scientists have a good understanding of how air pollution impacts human health and the terrestrial biosphere, but what impact does air pollution have on oceans? To help answer this question, this past August, researchers from Penn State's Department of Meteorology embarked on a three-week, NSF-funded field project to catch and analyze rainwater at sea.

Responding to the impact that a growing population and changing land use have had on the Chesapeake and Delaware Bays over the past 60 years is the focus of a research project led by Penn State and supported by a $1.4 million grant from NASA.

Some days cutting-edge research, in order to move forward, needs a little blast from the past. Penn State oceanographer Ray Najjar studies estuaries: coastal waters that mingle salt water with fresh, and are home to rich and complex ecosystems. In particular, he's interested in how these vital bodies may be impacted by climate change.
After years of focus on the Chesapeake Bay, the largest estuary in the United States, Najjar recently turned his attention to the neighboring Delaware Bay, and to possible changes in its salinity, which could have significant impacts on marine species and humans alike.

Changes in the ratio of nitrate to phosphorus in the oceans off the coasts of Korea and Japan caused by atmospheric and riverine pollutants may influence marine ecology and the makeup of marine plants, according to researchers from Korea and the U.S.

While global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation.
Researchers from Penn State and the University of Maryland Center for Environmental Science are studying the Chesapeake Bay to see how changes in sea level may have affected the salinity of various parts of the estuary.
